BackgroundThe ideal surveillance strategy after partial pancreatectomy for non-invasive IPMN remains undefined and existing guidelines provide conflicting recommendations. The present study was developed in anticipation of the joint meeting of the International Association of Pancreatology (IAP) and the Japan Pancreas Society (JPS) held in Kyoto in July 2022.MethodsAn international team of experts developed the four clinical questions (CQ) to operationalize issues pertaining to surveillance of patients in this context. A systematic review was designed following the PRISMA guidelines and registered in PROSPERO. The search strategy was executed in PubMed/Medline (Ovid), Embase, the Cochrane Library and Web of Science databases. Four investigators individually extracted data from the selected studies and drafted recommendations for each CQ. These were subsequently discussed and agreed upon that the IAP/JPS meeting.ResultsFrom a total of 1098 studies identified through the initial search, 41 studies were included in the review and informed the recommendations. No studies providing level one data were identified in this systematic review, all studies included were cohort or case-control studies.ConclusionsThere is a lack of level 1 data addressing the issue of surveillance of patients following partial pancreatectomy for non-invasive IPMN. The definition of remnant pancreatic lesion in this setting is largely heterogeneous across all studies evaluated. Herein we propose an inclusive definition of remnant pancreatic lesions to guide future prospective efforts for reporting the natural history and long-term outcomes of these patients. 相似文献

BackgroundPatients with low-risk lesions require ongoing surveillance since the rate of progression to pancreatic cancer (PC), while small, is much greater than in the general population. Our objective was to study the relationship between new onset diabetes (NODM) and progression in patients with low risk mucinous cysts.MethodsWe evaluated a prospectively maintained cohort of 442 patients with a suspected mucinous cyst without worrisome features (WF) or high-risk stigmata (HRS). Multivariable Cox models were developed for progression to WF and HRS, with diabetes status formulated as both time independent and dependent covariates. The adjusted cumulative risk of progression was calculated using the corrected group prognosis method.ResultsThe 5-year cumulative progression rates to WFs and HRS were 12.8 and 3.6%, respectively. After controlling for other risk factors, the development of NODM was strongly associated with progression to HRS (HR = 11.6; 95%CI, 3.5–57.7%), but not WF. Among patients with the smallest cysts (<10 mm) at baseline, those who developed NODM had a 5-year adjusted cumulative risk of progression to HRS of 8.6% (95%CI, 0.0%–20.2%), compared to only 0.8% (95%CI, 0.0%–2.3%) for patients without NODM. Among patients with the largest cysts (20–29 mm), those who developed NODM during surveillance had a 5-year adjusted cumulative risk of progression of 53.5% (95%CI, 19.6%–89.9%) compared to only 7.5% (95%CI, 1.6%–15.2%) for patients without NODM.ConclusionNew onset diabetes may predict progression in patients with low risk mucinous cysts. Pending validation with large-scale studies, these findings support regular diabetes screening among patients surveilled for suspected IPMNs or MCNs. 相似文献

BackgroundMalnutrition and bone disease are common in adults with chronic pancreatitis (CP). We studied the nutritional status and bone mineral density (BMD) of children with CP and the factors predicting them.MethodsCP children were prospectively evaluated with a detailed questionnaire, anthropometry, 25-hydroxy vitamin D, fecal elastase and BMD [total body less head (TBLH), spine and hip] by dual energy x-ray absorptiometry. Body mass index (BMI) Z score of ?1 to ?1.9, ?2 to ?2.9 and <-3 was taken as mild, moderate and severe malnutrition respectively. Low BMD and osteoporosis were defined as per International Society for Clinical Densitometry.Results83 children (46 boys, 14[4.3–21]years) with CP were enrolled. Majority had Cambridge IV (51,62.2%) or III (15,18.3%) changes. 34(41%) had undernutrition (mild-37.3%, moderate-2.4%, severe-1.2%). Overweight and obesity were present in 3.6% and 1.2% cases. BMI had a significant correlation with haemoglobin, serum albumin, percentage body fat and BMD. A majority had low fecal elastase (69 [84.1%], <100 μg/g) and vitamin D deficiency (70[84.3%],<20 ng/ml). 9 cases had a history of fractures. 14/75(18.6%) cases had low TBLH-BMD and this group had a lower BMI (?1.3[-1.9 to 0.34] vs 0.8 [-2.1 to 5.50; p = 0.03) than patients with normal BMD. There was no difference in age, disease duration, vitamin D, fecal elastase and Cambridge grade between normal and low BMD.Conclusions41% CP children have undernutrition with a majority having mild undernutrition. Nearly 20% have low BMD, with osteoporosis in none. Subjects with low BMI have lower BMD and percentage body fat. 相似文献

PurposeThe present study aimed to research the relationships between arterial lactate levels and pancreatic infection in moderately severe acute pancreatitis.MethodsThis study retrospectively analyzed data from 503 patients with moderately severe acute pancreatitis from January 1, 2013, to March 31, 2018. The baseline characteristics on admission were compared between patients with and without elevated arterial lactate levels. The parameters and laboratory data were compared between patients with and without pancreatic infections at admission. Univariate and multivariate logistic regression analyses were used to assess the value of elevated arterial lactate levels for identifying high-risk patients. P ≤ 0.05 was considered statistically significant.ResultsA total of 49 (9.2%) patients were diagnosed with pancreatic infections. Compared with patients without pancreatic infections, pancreatic infection patients had significantly increased arterial lactate levels at admission (1.5 ± 0.7 vs. 2.5 ± 0.9; P < 0.01). Multivariate logic analysis still showed that higher arterial lactate levels in moderately severe acute pancreatitis was an independent risk factor for developing pancreatic infections (hazard ratio: 6.31, 95% CI 3.01–13.24; P < 0.01). Arterial lactate level ≥2.1 mmol/L and procalcitonin level ≥0.5 ng/mL at admission had area under the receiver operating characteristic curves of 0.83 and 0.72, with sensitivity of 67.2% and 87%, and specificity of 82.0% and 60%, respectively, for the prediction of pancreatic infection in moderately severe acute pancreatitis.ConclusionsOur results indicate that a higher arterial lactate level is independently associated with pancreatic infection in patients with moderately severe acute pancreatitis and may be used as a tool to identify high-risk patients. 相似文献

BackgroundChronic pancreatitis (CP) may cause intermittent or continuous pain and complications requiring invasive interventions. No specific recommendations for surgical interventions have been presented. Our aim was to determine the surgical treatment strategies for the treatment of CP in the Scandinavian and Baltic countries.MethodsThis multi-centre cross sectional study included 1327 CP patients from eight centres. The data was gathered from the Scandinavian Baltic Pancreatic Club (SBPC) database. Patients who underwent pancreatic surgery were analysed. The baseline CP population from the eight centres was used as a reference. The information registered included comorbidities, pancreatic function, previous interventions, time and type of surgery and the EORTC-30 quality of life (QOL) questionnaire.ResultsOverall, 95/1327 (7%) patients underwent pancreatic surgery. Fifty-one (54%) of these underwent pancreatic surgery for chronic pain (PSCP) and formed the final study group. Median follow-up time was two (range 0–8) years after surgery and seven (1–46) years after diagnosis. The most common surgical procedures were pancreatic resection combined with drainage (54%) followed by pancreatic resections (32%) and drainage procedures (14%). Postoperatively, 47% of the patients were pain free with or without pain medication while 16% had chronic pain episodes, this did not differ from the base CP population. In QOL questionnaires, PSCP patients reported the same QOL but worse social functioning and more symptoms compared to the CP population.ConclusionsPancreatic surgery for CP is rare: surgical procedures were performed on only 7% of the CP patients in the SBPC database. In half of the patients the indication was pain. Most of these patients underwent endoscopic procedures before surgery. Half of the patients reported being pain-free after surgery. 相似文献

Background/Objective: The extent of exocrine pancreatic insufficiency (EPI) in the paediatric population with acute pancreatitis (AP) is unknown. The primary objective was to use a 6 h stable-isotope breath test to determine the prevalence of EPI in children with AP. The secondary objective was to determine the diagnostic ability of a 4 h abbreviated breath test in the detection of EPI.Methods13C-mixed triglyceride (MTG) breath test was used to measure fat digestibility in 12 children with AP and 12 normal children. EPI was diagnosed based on a cumulative dose percentage recovery (cPDR) cut-off value < 26.8% present in literature. To reduce the test burden, the diagnostic accuracy of an abbreviated 4 h test was evaluated, using a cPDR cut-off that was the 2.5th percentile of its distribution in control children.ResultsThe cPDR of cases was significantly lower than that of controls (27.71 ± 7.88% vs 36.37 ± 4.70%, p = 0.005). The cPDR during acute illness was not significantly different to that at 1 month follow up (24.69 ± 6.83% vs 26.98 ± 11.10%, p = 0.52). The 4 h and 6 h breath test results correlated strongly (r = 0.93, p < 0.001) with each other. The new 4 h test had 87.5% sensitivity and 93.8% specificity for detecting EPI.ConclusionTwo-thirds (66.7%) of this sample of children with AP had EPI during admission, which persisted at 1 month follow up. The 4 h abbreviated 13C-MTG breath test has good diagnostic ability to detect EPI in children and may improve its clinical utility in this age group. 相似文献

BackgroundGenetic mutations in various pancreatic enzymes or their counteracting proteins have been linked to chronic pancreatitis. In particular, variants in the genes encoding pancreatic lipase (PNLIP) and carboxyl ester lipase (CEL) have been associated with pancreatitis. Therefore, we investigated pancreatic phospholipase A2 (PLA2G1B) as a promising candidate gene in patients with chronic pancreatitis.MethodsWe analyzed all coding exons and adjacent intronic regions of PLA2G1B in 416 German patients with non-alcoholic chronic pancreatitis (NACP) and 186 control subjects by direct DNA sequencing.ResultsWe detected 2 frequent synonymous variants in exon 3: c.222T>C (p.Y74 = ) and c.294G>A (p.S98 = ). The genotype and allele frequencies of these variants were similar between patients and controls (c.222 TC: 9.6% in NACP vs. 9.7% in controls; c.222CC: 0.2% in NACP vs. 0% in controls; c.294 GA: 31.3% in NACP vs. 28.0% in controls; c.294AA: 2.4% in NACP vs. 1.1% in controls). All p-values were non-significant. In addition, we found one synonymous variant, c.138C>T (p.N46 = ) and one non-synonymous variant, c.244A>G (p.S82G), in a single case each.ConclusionsOur results suggest that genetic alterations in PLA2G1B do not predispose to the development of non-alcoholic chronic pancreatitis. 相似文献

Background & aimFatty acid ethyl esters (FAEEs), are produced by non-oxidative alcohol metabolism and can cause acinar cell damage and subsequent acute pancreatitis in rodent models. Even though experimental studies have elucidated the FAEE mediated early intra-acinar events, these mechanisms have not been well studied in humans. In the present study, we evaluate the early intra-acinar events and inflammatory response in human pancreatic acinar tissues and cells in an ex-vivo model.MethodsExperiments were conducted using normal human pancreatic tissues exposed to FAEE. Subcellular fractionation was performed on tissue homogenates and trypsin and cathepsin B activities were estimated in these fractions. Acinar cell injury was evaluated by histology and immunohistochemistry. Cytokine release from exposed acinar cells was evaluated by performing Immuno-fluorescence. Serum was collected from patients with AP within the first 72 h of symptom onset for cytokine estimation using FACS.ResultsWe observed significant trypsin activation and acinar cell injury in FAEE treated tissue. Cathepsin B was redistributed from lysosomal to zymogen compartment at 30 min of FAEE exposure. IHC results indicated the presence of apoptosis in pancreatic tissue at 1 & 2hrs of FAEE exposure. We also observed a time dependent increase in secretion of cytokines IL-6, IL-8, TNF-α from FAEE treated acinar tissue. There was also a significant elevation in plasma cytokines in patents with alcohol associated AP within 72 h of symptom onset.ConclusionOur data suggest that alcohol metabolites can cause acute acinar cell damage and subsequent cytokine release which could eventually culminant in SIRS. 相似文献

ObjectivesThis study sought to evaluate the prevalence and patterns of late gadolinium enhancement (LGE) after carbon monoxide (CO) poisoning using cardiac magnetic resonance (CMR) imaging (CMRI) and transthoracic echocardiography (TTE).BackgroundIn acute CO poisoning, cardiac injury can predict mortality. However, it remains unclear why increased mortality and cardiovascular events occur despite normalization of CO-induced elevated troponin I (TnI) and cardiac dysfunction.MethodsPatients with acute CO poisoning with elevated TnI were evaluated. CMRI was performed within 7 days of CO exposure and after 4 to 5 months. Patients were divided into LGE (n = 72; 69.2%) and no-LGE (n = 32; 30.8%) groups.ResultsIn the LGE group, 39.4%, 4.8%, and 25.0% of patients exhibited midwall, subendocardial, and right ventricular insertion point injury, respectively. Diffuse injury was observed in 22.1% of patients, and 67.6% of the 37 patients who underwent follow-up CMRI showed no interval change. On TTE, baseline left ventricular ejection fraction and global longitudinal strain were significantly deteriorated in the LGE group; serial TTE within 7 days indicated that only left ventricular global longitudinal strain remained significantly deteriorated. Three cases of mortality occurred in the LGE group during the 1-year follow-up.ConclusionsThe LGE prevalence in patients with acute CO poisoning with elevated TnI levels, with no underlying cardiovascular diseases and eligible for CMRI, was 69.2%; this proportion primarily comprised patients with a midwall injury. Of the 37 patients who underwent follow-up CMRI, most chronic phase images showed no interval change. Myocardial fibrosis detected on CMR images was related to acute myocardial dysfunction and subacute deterioration of myocardial strain on TTE.

ObjectivesThe aim of this study was to characterize the feasibility of coronary angiography (CA) and percutaneous coronary intervention (PCI) in acute settings among patients who have undergone transcatheter aortic valve replacement (TAVR).BackgroundImpaired coronary access after TAVR may be challenging and particularly in acute settings could have deleterious consequences.MethodsIn this international registry, data from patients with prior TAVR requiring urgent or emergent CA were retrospectively collected. A total of 449 patients from 25 sites with acute coronary syndromes (89.1%) and other acute cardiovascular situations (10.9%) were included.ResultsSuccess rates were high for CA of the right coronary artery (98.3%) and left coronary artery (99.3%) and were higher among patients with short stent-frame prostheses (SFPs) than in those with long SFPs for CA of the right coronary artery (99.6% vs 95.9%; P = 0.005) but not for CA of the left coronary artery (99.7% vs 98.7%; P = 0.24). PCI of native coronary arteries was successful in 91.4% of cases and independent of valve type (short SFP 90.4% vs long SFP 93.4%; P = 0.44). Guide engagement failed in 6 patients, of whom 3 underwent emergent coronary artery bypass grafting and another 3 died in the hospital. Among patients requiring revascularization of native vessels, independent predictors of 30-day all-cause mortality were prior diabetes, cardiogenic shock, and failed PCI but not valve type or success of coronary engagement.ConclusionsCA or PCI after TAVR in acute settings is usually successful, but selective coronary engagement may be more challenging in the presence of long SFPs. Among patients requiring PCI, prior diabetes, cardiogenic shock, and failed PCI were predictors of early mortality. 相似文献

BackgroundChronic pancreatitis (CP) patients have a high prevalence of osteoporotic fractures. In addition to prevalence of osteoporotic fractures, we evaluated how often bone health is assessed by dual-energy x-ray absorptiometry (DXA) in clinical practice, and the performance of Fracture Risk Assessment Tool (FRAX®) in predicting fracture risk in CP patients.MethodsMedical records of CP patients age ≥40 years prospectively enrolled in the North American Pancreatitis Study 2 (NAPS2) from the University of Pittsburgh Medical Center from 2000 to 2014 were retrospectively reviewed to gather additional relevant data before, at, and after enrollment until December 2016. We determined if patients underwent DXA, compared their observed prevalence of fractures with published data from two large US studies based on administrative data, and their predicted fracture risk with US population based on FRAX®.ResultsOnly 21% (49/239) patients were evaluated by DXA during their care. The observed cumulative prevalence of fragility fractures in NAPS2 CP patients (9.2%, 95% confidence interval 5.9–13.6) was significantly greater than in controls (1.46% and 2.16%, p ≤ 0.001 for each comparison) and CP patients (4.66%, and 5.13%, p < 0.005 for each comparison) in the two US administrative data studies. The FRAX® 10-year probability of major osteoporotic fracture of ≥20% (5.1% vs. 8.3%, p > 0.05) and for hip fracture of ≥3% (19.6% vs. 18.9%, p > 0.05) in NAPS2 CP patients did not differ from the US population.ConclusionsDespite their high risk of fragility fractures, bone health is infrequently assessed in CP patients. FRAX® may not adequately predict fracture risk in CP patients. 相似文献
